8. For example [Ni(cyclam)]2+ catalyses the electrochemical reduction of CO2 to CO;M. P., Beley, J. P., Sauvage, J. Chem. Soc., Chem. Commun., 1984, 1315. This reduction has also been performed photochemically, using [Ru(bipy)3]2+ as a photosensitiser, [Ni(cyclam)]2+ as the catalyst, and ascorbic acid as a sacrificial electron donor

Commun., 1985, 684, except that the free radical reaction was initiated by a Xenon lamp. The product was isolated from the reaction mixture by crystallisation from diethyl ether. (CAUTION! In common with other halomethyl pyridines, 5-bromomethyl-2,2′-bipyridyl is an extreme irritant.)
